I know this answer is probably late but here it goes:
No, they are different products. AFAIK "Fuse ESB Enterprise" is the RedHat Fuse you're finding. RedHat Fuse is an ESB technology running on top of Apache Karaf - the OSGi server - while RedHat FuseServiceWorks runs on top of JBoss EAP - the JEE6 server. Additionally, FuseServiceWorks includes the Fuse ESB technologies (e.g. Camel, CXF and ActiveMQ) + SwitchYard and Overlord. Having said that, there are basically two questions I would ask to decide which one to choose:
- Is it a requirement to deploy your projects on a OSGi environment?
- Will you need a governance technology such as Overlord?
If your answer is YES to the first question and NO to the second one, pick Fuse. If you need JEE and/or governance, FuseServiceWorks is what you're looking for.
